ZA 4 LT Red (4 ShA)

ZA 4 LT RED is a bi-component addition cured RTV silicone rubber which vulcanizes at room temperature. Due to the considerable fluidity it is recommended for the duplication of models with accentuated undercuts. Compatible with all plasters, coatings, polyurethane resins and acrylic resins.

Main application sectors

Mouldmaking and model-making due to its considerable precision in reproduction, high dimensional stability and high mechanical resistance

Ceramic serigraphy due to its considerable precision in reproduction, high mechanical resistance and excellent laser cutting characteristic
